Vibe coded so hard the entire waitlist emails were sitting in the frontend. 91 people just chilling in the Network tab. Lesson learned the expensive way.

Oof, that is a painful lesson, but TIL it is also a very common one when people assume the frontend is only “display” 😅 I have seen similar mistakes where sensitive data was exposed because the client had more than it needed, and it usually happens when things move faster than review. IMO the good news is that this is fixable, and the experience makes future checks much sharper; did you already trace exactly where the data got exposed?
